Topic: Permission denied (publickey)

[ElFroggio]

SME 9.1

Today I tried to log on through the web interface and it wouldn't, so I did ssh admin@192.168.1.14 and got the following message:

Code: [Select]

ssh admin@192.168.1.14
Permission denied (publickey).
When login as root I have no problem. I reset the admin password just in case. But 'no dice'.

Last login from admin was 2 days ago and it was successful and as far as I know, nothing has changed.

Code: [Select]

I have checked my .ssh local directory and it's identical to my previous weekly backup, when it was working

Here is root which works:

Before editing configuration files, familiarise

The <<<< are the difference. Why?

Thanks

try 'ssh root@YOURIP'

[ElFroggio]

try 'ssh root@YOURIP'

It works.

For me the problem is the admin account. I can't connect, I can't log in through the web interface: server-manager

Thanks

Syv

[Stefano]

ok..

how did you change admin's password (see your initial post)?

[Stefano]

BTW, you can log in in ssh as root and then use

Code: [Select]

console

to reach the console and

Code: [Select]

elinks

to see server-manager..

[Stefano]

and, finally, did you follow the wiki's advice?

Yes that work when I'm at the server console.

But I still can't logon from my computer (on the local network) to server-manager (chromium & firefox)

Yes.

[Stefano]

ok..

can you access server-manager from elinks?

[ElFroggio]

ok..

can you access server-manager from elinks?

Yes at the console, no at my desk.

Which log file keeps track of the web failed/errors for signing in into server-manager?

Thanks

Syv

[Stefano]

well.. elinks is a browser.. a text one, but a browser.. if you can log in in server-manager using elinks it means that authentication is working..

I guess it's something related to your client.. or to something you did..

can you give us as much details as you can, please? did you try from another client? with a different browser?

[Stefano]

and, please, give us details abou

Today I tried to log on through the web interface and it wouldn't

what do you see in the browser? can you reach server-manager? if you try to authenticate, which error message do you see?

please, be verbose, we can't see your screen, we don't know anything about your server.. help us to help you, thank you

Here's the screen capture after trying to login as admin: http://i.imgur.com/x5FvidH.png

I do not see any error message. That's why I was asking which log file would record/debug the failure.

Tonight when I get back my laptop, I try another it on it.

Thanks
